摘要: In order to estimate the importance of atmospheric fall-out persistent organic pollutants (POPs) around industrial district Porto Marghera, Italy, depositions POPs were collected using bulk samplers inside Lagoon Venice. Seventy-seven deposition samples monthly over a 12-month period (March 2003-March 2004) at seven sites located close area Marghera. Samples analysed by HRGC/HRMS for PCDD-Fs, PCBs, HCB and PAHs. Differences in mean daily fluxes all between industrial, urban lagoonal stations clear, being higher than target values dioxin recommended EU strategy on dioxins, furans polychlorobiphenyls. calculate loadings district, we considered an defined distance 10 km from hypothetical centre-point main sources emissions The calculated loadings, compared with previous estimates, show that annual are 12, 510, 90 130 kg PAHs, respectively, corresponding 350-500 mg TEQ, thus indicating slight decrease PCBs great respect 1998-99. input coming atmosphere is same magnitude due watershed runoff approximately one-half direct discharges.
